Re: 2008 imac won't start

Hi John, I gave up on “shadetree” BGA reflows years ago, but YMMV. My reflows worked for a while, then died for good. Another issue with the 2008-era iMacs is that occasionally the “coolant” (ether, I’m told) leaks out of the tubes running to and from the fins and the heat sink proper. Same
